Structural investigations under high pressure conditions

Because of its extremely high yield strength, hardness and relatively high transparency to high-energy x-ray radiation, the diamond anvil cell has become a favored device in high pressure research. This includes structural investigations where pressure induced phase transitions can be studied using x-ray diffraction techniques up to several Mbars when …

The representation of thermodynamic properties at high pressures

1. INTRODUCTION The thermodynamic properties of a system can be rep- resented in several ways. Since pressure and temper- ature are constant under many conditions of practical importance, it is common to use the Gibbs energy for such representations. By giving the molar Gibbs energy of a substance as a function of …

Visible and near-infrared optical-absorption edges of TlCl, TlBr, and TlI were measured as a function of pressure in a diamond anvil cell. The indirect band gap of the three thallous halides shifts red (to lower energy) with pressure and was followed into the near infrared. The direct band gaps of TlBr and TlCl also shift red at a slower rate. The calculated band …
